updated a 10.5.1 on MacBookPro 2,6Ghz, with many programs installed (say : Office 2008, Adobe CS3 suite, iLife 08, iWork 08, Final Cut and some 40 additionnal ... , plus usual intensive web and mail, and plug-ins ; not really a standard configuration, I'd say, with 3 regularly used different network configurations - 1 Ethernet, 2 Wi-Fi)

So far so good ; install was a breeze, 2 restarts and running. I regret that Safari 3.1 was not added, but ... this comment was just to say something a bit negative, otherwise you would find my review suspicious...
